A typical exploit landing page looks like this [URLquery report] which appears to be the Nuclear EK.

These are hosted on the following Choopa LLC / Gamservers.com IP addresses (it is the same company with two different trading names) [clicking the IP leads to the VirusTotal results, ones identified as malicious are highlighted]:

As I said, these domains see to have a very short life. I identified nearly 3000 domains using these nameservers, the following of which are flagged as malicious by Google (long list, sorry, scroll past it if you like):

These are the TLDs and SLDs being abused, operated by Freenom (cf, ga, gq, ml, tk) or CoDotVu (co.vu). It looks like perhaps Freenom cleaned up their space, but you can make your own mind up if you want to block traffic to these as a precaution: co.vucfgagqmltk

A full list of all the domains that I can find associated with these servers can be found here [pastebin].
